• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

Hi guys,

I hope you can help me out with this little problem I'm having.
Here's my pilot in FSX:SE:

Converting everything to P3Dv4, now my pilot looks like this:

Any idea what could cause this and how to fix it?
 
Hello Vitus...

Looks like he had gone through the twilight zone :)

I take it that you are converting through Blender? and that the textures were untouched? The head on the model is also animated?
 
Yes, yes and yes.
It's a skinned mesh, animated through an armature. The material is a simple specular one, with only a diffuse texture added, no specular, no bump map.

I thought it might be some double-faces, but I cleaned up the model and there shouldn't be any overlaps of that kind. I have no clue where this is coming from...
 
My guess would be a weight issue then, one or a couple of armatures are out of sync with the rest of.
 
I tested your idea by removing the armature and unticked the "skinned mesh" parameter in the material settings. And it looks like you're right - it looks OK without the skinned mesh.
But what am I doing wrong with the armature in the first place? What should I look for? I checked the weights, they look fine.
 
It might be nothing, but... I once had this precise issue with an un-animated mesh, whereby a bump map without an alpha caused the same effect. Added the alpha ( just the same image converted ) and the shading disappeared. Worth a try to see if it's an easy fix and the result of P3D's lighting system rather than a problem with the armature itself.
